SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 371,255, dated October 11, 1.887.

Application filed J une 24, 1887. Serial No. 242,397. (Model.)

To all whom t may concern.-

Be it known that we, GHARLEs MORGAN DRINKER and RODMAN M. DRINKER, citizens of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented a new and useful Improvement in Seal-Locks, of which the following is a specification.

Our invention relates to an improvement in seal-locks; and it consists in a certain novel construction and arrangement of parts fully set forth hereinafter, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of the seal-lock. Fig. 2 is a longitudinal section of the same. Fig. 3 is a similar view with the shackle released. Fig. 4 is a reversed plan view of the lock. Fig. 5 is a side view of the key.

Referring by letter to the drawings, the body A of our improved seal-lock comprises the head B, having a circular lower side, and the parallel arms O C, formed integrally with the said head, the said head being provided with a vertical central opening, b, for a purpose to be explained. The said head B is provided with a hollow space or opening, B', communieating with the central opening, b, therein, and in the said opening B is pivoted the dog D, having the lateral arm d extending therefrom, which is adapted, when the said dog is repressed, to compress the spiral spring d', which is disposed between the end of the said arm d and the upper side of the open space or opening B'. The said dog projects out slightly into the central opening, b, in the head, for a purpose hereinafter explained.

c care depending lugs on the arms C C, near the head, and the said lugs are provided with aligned perforations.

E designates the shackle of the lock, pivoted at its rear end between the extremities of the arms C C, and fitting at the other end in the central opening, b, in the head of the lock. The said rear or pivoted end of the shackle is provided with the angle arm or lug F, formed on the side of the said shackle and extending toward the head of the body of the lock. The arm F is provided with a rabbet or recess, f', on the lower side of the extremity u thereof. The locking end of the shackle is provided with the notch e, adapted to receive the dog D, and the narrow slit c', communieating with the said notch and adapted to receive a key to repress the said dog. key G is provided with the straight shank g, the lower or engaging end of which is straight on one side, while the other side is beveled to reduce the said shank to a point. The said key is inserted into the slit e' in the end ofthe shackle, with the straight side thereof toward the dog D, and when the key is pressed in or upwardly the beveled side thereof, sliding on the beveled side of the slit e', presses the said dog out of engagement with the notch and allows the shackle to be opened.

H designates the locking-arm for the seal, and it comprises the lever-arm h, pivoted between the lugs c c on the lower side of the arms, O Gand the ring H on the end thereof, which corresponds in size to the circular lower side or seat of the body of the lock. The said lever-arm extends rearwardly under the lower side of the arm F, which is on the pivoted end of the shackle, and the strong spring I is secured at one end rigidly to the upper side of the 1ever-arm,near the pivot thereof, and bears at the other end in the rabbet or recess f in the lower side of the said arm F. It will be seen that the tendency of this springis to force the extremity of the lever-arm h downwardly, and at the same time to force the arm F of the shackle upwardly,and therefore when the locking end of the shackle is released the spring will canse the said shackle to be thrown back.

It will be seen that when the shackle is locked in place the arm F bears down tightly upon the upper side of the extremity of the lever-arm h, and therefore holds the ring H at the other end of the said lever-arm tightly pressed against the seat on the under side of the head of the lock. The said seat a is provided around its outer edge with the annular `fiange a', and the upper edge of the ring H is beveled on the outer side to lit within the said iiange a on the seat, while the inner edge of The said u It will be seen that it is impossible for the' seal to be extracted after the shackle has been locked,for the beveled upper edge of the ring iits within the annular iiange of the seat, and thus prevents the insertion of a tool.

Ihe only manner in which the lock can ben opened after the seal is locked in place is by forcing the sharpened end of the key through the said seal and inserting it into the slit in the end of the shackle in the manner hereinbefore described.

The construction of our lock is very simple and it is very easily operated by the proper means; but it will be seen that when the seal is secured in place there is no possible way in which the lock can be opened without breaking said seal, as the parts of the lock are made suciently strong to resist any ordinary attempts to break or open it.

The opening B in the head of the lock, containing the locking-dog,is inclosed separately from the other portion of the lock, both to prevent the weather from gaining access to the locking mechanism and to prevent the locking-dog from being tampered with. It will be seen, however, by referring to Fig. 2, that the top plate of the said opening B is riveted in place, and was so secured after the said locking mechanism was inserted.

rI"he lever-arm, as will be seen, is securely riveted in place, and it is not necessary to inclose this portion of the lock, as it is evident that as the under side of the arm F presses down tightly on the extremity of the lever-arm there is no possibility of the ring at the other end of the lever-arm being lifted.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

l. In a seal-lock, the combination, with the body A and the shackle E, of thelocking-arm H, adapted to hold the seal in place and be operated by said shackle to release or lock the seal when the shackle is unlocked or locked, substantially as specified.

2. In a seal-lock, the combination, with the body A, of the shackle E and the locking-arm H, comprising the lever-arm 7L, pivoted in said body, and operated at one end by said shackle, and the ring H at the other end, to contain the seal, adapted, when the shackle is locked in place, to press tightly over the entrance to the key-hole of the lock, substantially as specified.

3. In a seal-lock, the combination, with the .body A and the shackle E, pivoted at one end to the body, and adapted to be locked at the other end in said bddy, and having an angle-arm, F, on the pivoted end thereof, ofthe locking-arm H, having the lever-arm h, piv- Y oted in the body and projecting under the arm F of the shackle at one end, and the spring I, secured to the said arm h, and bearing at the end against the arm F, said locking-arm H being adapted to lock the seal in place, substantially as specified.

4. In a seal-lock, the combination, with the body'A, having the head B, provided with an annular flange, c', and a central opening therein, and the shackle pivoted to the said body and adapted at one end to enter and be locked in the said opening in the head, of the locking-arm H, pivoted to said body, and having the ring H, to carry the seal and bear against the circular lower side of the head when the shackle is locked in place, the upper edge of the said ring being adapted to fit within the flange a', as and for the purpose set forth.

5. The combination, in a seal-lock, with the body A, having the opening b at one end, and the shackle E, pivoted at the other end of said body, and adapted to enter at its free end said opening, of the spring-actuated dog D, pivoted in the body and adapted to engage the free end of the shackle, and the lockingarm H, pivoted to the body and adapted to bear against the same over the opening b and hold the seal firmly in place over the said opening, substantially as specified.
